JOSEPH GREENWOOD AND \VILLIAM HILL, JR, OF LIMESTONE, NEW YORK.

WINDMILL ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 356,246, dated January 18, 1887",

Application filed August 14, 1886. Serial No. 210,922. (No model.)

To all whom it may concern.-

Be it known that we, J OSEPH GREENWOOD and WILLIAM HILL, J r., of Limestone, in the county of Oattaraugus and State of New York, have invented a new and Improved Windmill Attachment, of which the following is a full,

clear, and exact description.

Our invention relates to attachments for increasing the length of stroke in various machines, particularly in connection with pumps operated by windmills; and it has for its object to effect in the stroke of windmills and other equivalent engines decided increase in a simple and effective manner; also, to so balance the rods used in connection with a windmill to impart and receive power as that the weight of said rods will'not retard the movement or interfere with the operation of the windmill in any degree.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of our windmill attachment, and Fig. 2 is an edge view of one of the connecting-rods used therein. Fig. 3 is a section through line mm of Fig. 1.

A represents a slotted standard, adapted to be fastened to the derrick or tower of a windmill, near the upper portion of which standard, within its slot a, a lever, B, is pivoted by means of a bolt, a, passing through the standard A and the metal cap I), bolted to the upper edge of said-lever B.

The rod 0, pivotally connected to the lever B through the medium of a metallic plate provided with a central projection, c, bolted to the upper edge of said lever, near the working end thereof, communicates motion thereto from the windmill or other motive power used in connection therewith.

At one side of the center of the space between the communicating-rod O and the slotted standard A, nearer the standard, a connecting rod, D, is pivoted at one end to the under side of the lever B, to extend downward at a slight angle, and be pivotally connected at the other to the top of a lower short lever, E, close to the end thereof, facing the standard A, the said lever being held a proper distance from said standard by a hook secured to the standard A, entering an eye in the aforesaid end of the lever E.

- The connecting-rod D is formed of two pieces, as shown in Fig. 2, having a central space, 6, between them, connected and strengthened by means of metal plates bb, extending nearly the entire length of said lever, upon each side thereof. A second outer connecting'rod, F, is pivoted to the under side of the long upper lever, B, at the working end thereof, to extend downward at a decided angle inward to form a pivotal connection with the upper side of the lower short lever, E, near the center thereof. G represents the pump-connection, pivoted, as shown, to the under side of the short lower lever, E, at its working end.

Our invention, as above described, would, through the action of the aforesaid levers and connecting-rods, lengthen the stroke of the windmill or attached engine; but in its application to windmills the mill would be cramped and burdened in working by carrying the weight of the rods. To overcome this objection we pivot a lever, H, within the slot at of the standard A, between the upper and lower levers, B and E, carrying the short arm h thereof through the space e of the connecting rod D, and pivoting the same centrally to the angular connectingrod F.- The long end h of the said lever H, extending outward from the slotted standard A, is adapted to have attached thereon a weight,'K, by means of a set-screw, k. This weight K is so positioned upon/the lever H as to perfectly balance the rods-G and G, removing thereby the weight of said rods from the windmill, thus allowing it to run easily.

The average stroke of a windmill is about five inches. When the rod 0 from the mill is connected, as shown in Fig. 1, the stroke of the pump-rod, due to the intervention of the levers and connecting-rods, arranged as de scribed, will be increased to about eleven inches, and the water pumped in proportion to the stroke.

The stroke is regulated by the angular connecting-rod F. The nearer the said rod F is 'moved toward the working end of the lever B the longer the stroke. When moved in direction of the communicating-rod O, the stroke becomes shorter.

\Vhile our invention is especially adapted for use with windmills, it is capable of use with any machine to increase the stroke, and is particularly adapted for pumping machinery.

All the pivotal connections are made thro n gh metal plates bolted to the levers and bars, having central apertured projections, c.

Having thus fully described ourinvention, what-we claim as new, and desire to secure by Letters Patent, is

1. The combination, with the slotted standard A, having pivoted thereto the upper lever, B, and communicatingrod O, of the connecting-rod D, connecting-rod F, and lever E, detachably connected to said standard .A, together with the lower communicating-rod, G, substantially as shown and described, and for the purposes herein set forth.

2. The combination, with a device for length- XVitnesses:
